The cellular environment contains ions, or , that are used by the cell for different purposes, depending on its needs. These ions include sodium, potassium, calcium, bicarbonate, chloride, and phosphorus. Their electrical charges must remain in balance on either side of the cell membrane.

There must be a balance of compounds on either side of the cell membrane. If an imbalance occurs, the cell can move chemicals or charges across its membrane by various methods, including diffusion, filtration, , and osmosis.

Understanding the workings of and intracellular chemicals and charges will provide you with a better foundation for understanding why different types of IV fluids are administered for different conditions.

Becoming familiar with the various types of will give you an understanding of their use in relation to patient conditions.

Successful IV technique takes practice. Several factors, from the patient's condition to the available IV equipment, influence every IV start. Mastery of IV skills comes when you understand and can overcome all the variables. Take your time when practicing IV starts and gain a solid understanding of what you are doing. This understanding will be useful when you need to perform a quick and flawless IV start in less than optimum conditions.

Administering IVs to pediatric and geriatric patients requires special care. Both populations are at a higher risk for certain medical conditions that can affect both the patient's need for IV therapy and the effectiveness of the therapy. By understanding the risks and concerns of these populations, you will be better equipped to properly administer IV therapy. Finally, in any medical situation involving pediatric or geriatric patients, remember to be sensitive to the patient's personal issues.
